LAYING MACHINE GUIDE FOR WARP KNITTING MACHINES Filed Aprii 5, 195a Patented July 11, 1939 UNITED STATES PATENT OFFICE LAYING MACHINE GUIDE FOR WARP KNITTING MACHINES Emil Herbert Wirth,

Hartmannsdorf, near Application April 5, 1938, Serial No. 200,233 In Germany October 30, 1937 4 Claims.

The present invention relates to a guide of a laying machine for warp knitting machines.

The sliding bushings for the laying machines used hitherto in connection with warp knitting machines consist of two parts one of which is fixed in the guide bar holder, whereas the otheris connected by means of screws to the fixedly arranged part.

Besides the fact, that the loosening of the bushl-') ings for the purpose of withdrawing the guide of the laying machine is time consuming, these twopart sliding bushings still have the other great disadvantage, that they do not allow all parts of the bolts arranged in them to find' the required 1 complete rest.

Consequently, the high speeds used in modern warp knitting machines cause troubling noises and inaccuracies in the operation of the machine.

Now' the purpose of the invention is to obviate the above mentioned disadvantages. This is obtained according to the invention by the fact, that the sliding bushings of the guide are formed as a closed sleeves adapted to be withdrawn together with the guide, said sleeves may be fixed in the guide bar holder by means of web members or the like adapted to be held by screws.

In the accompanying drawing one construction according to the invention is shown by way of example.

In this drawing:

Fig. 1 is a front elevation of a'guide of a laying machine according to the invention,

Fig. 2 is a side elevation of the arrangement according to Fig. 1 partly .in section,

Fig. 3 is a front elevation of part of the arrangement disclosed in Fig. 1, showing the manner of loosening and fixing the sleeves, and

Fig. 4 is a side elevation of the holder which is fixed to the lever of the guide bar holder and supports the guide of the laying machine.

The guide of the laying machine consists in well known manner of a frame I carrying the bar 2 supporting the guides 3.

Journalled in the frame I' are hollow bolts 4 and 5 by means of which the guide of the laying machine is connected to the lever B of the guide bar holder.

The holder 1 is, as may be seen from Fig. 2,

' tending over their entire length. The width of the slots l0 and II is somewhat larger than the diameter of the hollow bolts 4 and 5.

Mounted upon each of the hollow bolts 4 and 5 is, according to the invention, a sliding bushing 5 l2 formed as a sleeve having a knurled head l3. The inner diameter of the bushing or sleeve l2 corresponds to the outer diameter of the holder bolts 4 and 5. The outer diameter of the sleeve I2 is equal to the inner diameter of the bearing 10 sleeves 8 and 9.

Each of the sliding sleeves I2 is provided on its outer surface with a flattened portion i4. A web member I6, consisting preferably of resilient material, is swingably connected to the holder 1 by means of a screw I5. The ends of the web member l6 may be pressed against the flattened portion M of the two sliding sleeves l2.

If the guide of the laying machine occupying the operative position shown in Fig. 1 is to be 20 withdrawn from the warp knitting machine, the screw I5 is loosened and the web member l6 brought into the position shown in Fig. 3, Whereupon the sliding sleeves I2 may be withdrawn from the bearing sleeves 8 and 9 by exerting a pull on the head l3. Thereupon the hollow bolts 4 and 5 of the frame I may readily be moved through the longitudinal slots Ill, ll of the bearing sleeves 8 and 9, that is to say, the guide of the laying machine may now without difiiculty be withdrawn from the warp knitting machine.

If new the guide of the laying machine is to be inserted again into the warp knitting machine, the bolts 4 and 5 are first moved through 35 the longitudinal slots III, II into the bearing sleeves 8, 9 in which they are sufliciently held until the two sliding sleeves l2 are shifted into the bearing sleeves 8, 9, the Web member 16 has been swung around the screw l5 into the posi- -40 tion shown in Fig. 1, and the screw l5 itself has been tightened.

What I claim is:

1. A support for a guide for a laying machine for warp knitting machines comprising a frame carrying said guide, closed sleeves slidably mounted upon a portion of said frame, a holder connected to the guide bar holder of said laying machine, sleeves each capable of receiving one of said closed sleeves carried by said holder and each having a longitudinal slot formed through one entire side thereof for receiving said portion of the frame therethrough and means for retaining said closed sleeves in their respective slotted sleeves.

2. A support for a guide of a laying machine for warp knitting machines comprising a frame carrying said guide, a pair of hollow bolts mounted on said frame, a pair of closed sleeves each slidably mounted upon-one of said hollow bolts, a holder connected to the guide bar holder of said laying machine, each end of said holder being in the form of a sleeve for receiving one of said closed sleeves, each of said holder sleeves having a longitudinal slot formed through one entire side thereof for receiving one of said hollow bolts therethrough and means for retaining said closed sleeves in their respective holder sleeves.

3. A support for a guide of a laying machine for warp knitting machines comprising a frame carrying said guide, a pair of hollow bolts mounted on said frame, a pair of closed sleeves each slidably mounted upon one of said hollow bolts, a holder connected to the guide bar holder of said laying machine, each end of said holder being in the form of a sleeve for receiving one' of said closed sleeves, each of said holder sleeves having a longitudinal slot formed through one entire side thereof for receiving one of said hollow bolts therethrough, each of said closed sleeves being provided with a flattened portion and means cooperating with said flattened portions for retaining said closed sleeves in their operative position in said bearing sleeves.

v 4. A support for a guide-of a laying machine for warp knitting machines comprising a frame carrying saidguide, a pair of hollow bolts mounted on said frame, a pair of closed sleeves each slidably mounted upon one of said hollow bolts, a holder connected to the guide bar holder of said laying machine, each end of said holder being in the form of a sleeve for receiving one of said closed sleeves, each of said holder sleeves having a longitudinal slot formed through one entire side thereof for receiving one of said hollow bolts therethrough each of said closed sleeves being provided with a flattened portion and a web pivotally mounted on said holder and being adapted to have its ends resiliently pressed against said flattened portions of said closed sleeves to hold said closed'sleeves in said bearing sleeves.
